Thanks, and I’d love to have additional Processing examples to include! Keep it up :)

Of course!
Every little helps :)

If I do any more that might be interesting I’ll post them up here and you can feel free to add them.

James,

Your example works great, and it’s a nice simple example of interactive 3D. I’d like to include it in the examples/ directory of the Incanter distribution, if it’s alright with you.

David, you were of course correct :)

I had actually tried that before after seeing it in your processing.clj file but I must have done something else wrong at the time as I thought that it wasn’t working.

So I put together a simple example from your simple_interaction.clj and the RGB cube example on the Processing site…

Might help people like me who are new to all this.

thanks again,

I haven’t worked with P3D or OpenGL within Processing yet, but I think the problem you’re experiencing is because you are passing “P3D” to the size function. Try passing the ‘constant’ P3D (which has the value “processing.core.PGraphics3D”). Let me know if this fixes your problem.

Good luck,
David

Hi again,

I wonder if you or any of your readers could help me with getting any of the 3d modes to work.

When defining the setup if I pass “P3D” as the third argument to size I get an error…

“Exception in thread “Animation Thread” java.lang.RuntimeException: You need to use “Import Library” to add P3D to your sketch.
at processing.core.PApplet.makeGraphics(PApplet.java:1193)”

Usually in processing P3D is available without importing.
I also tried OPENGL following the instructions in clj-processing about adding to the classpath etc but no joy.

If anyone can provide a simple example that would be great.

thanks,

James

All good!

Glad I could help.

D’oh! I forgot that the ‘save’ multi-method used the same dispatch logic. Fix uploaded, give it a try.

Thanks for the debugging help :)

although I just tried the us map data example and while it does run there is an error reported…

bin/clj examples/processing/us_map_data.clj
Exception in thread “Animation Thread” java.lang.IllegalArgumentException: No method in multimethod ‘save’ for dispatch value: class user.proxy$processing.core.PApplet$0

updated, rebuilt and it works great!

thanks for your great work.
